FOREWORD 

This Indian Standard was adopted by the Bureau of Indian Standards, after the draft finalized by the Fire 
Fighting Sectional Committee had been approved by the Civil Engineering Division Council. 

This standard is one of the series giving specifications for fire extinguishing media in common use and which 
are in need of specification for fire fighting purposes. These specifications are designed to establish that the 
medium in question has at least a minimum useful fire extinguishing capability andean, therefore, be reasonably 
used for fire extinguishing purposes. 

Annexes A to C of this standard specify methods for determining, respectively, water, oil and total sulphur 
compounds contents. Annexes D to G provide important information on and give recommendations relating to 
the safety and use of carbon dioxide, and they should be read carefully by all concerned with this medium. 

The composition of the Committee for the formulation of this standard is given at Annex H, 

For the purpose of deciding whether a particular requirement of this standard is complied with, the final value, 
observed or calculated, expressing the result of a test or analysis, shall be rounded off in accordance with 
IS 2 : 1960 'Rules for rounding off numerical values (revised)'. The number of significant places retained in 
the rounded off value should be the same as that of the specified value in this standard.

8 SAMPLING 

8.1 General 

Samples of carbon dioxide needed to perform all the 
tests required by this standard shall be taken from the 
same manufacturing lot, using identical sampling 
procedures. 

NOTE — Attention is drawn to the need to design equipment for 
handling carbon dioxide such that it is either capable of 
withstanding the pressures involved or protected from them. 

8.2 Sampling Equipment 

Rigid metal connections or flexible reinforced nylon 
hose should be used throughout the sampling 
equipment and shall be kept as short as possible. All 
components shall have a design pressure of not less 
than 137 bar. 

8.3 Procedure 

8.3.1 General 

Two methods of sampling are specified as follows: 

a) Direct sampling, in which the sample is 
passed to an evaporator and then directly to 
the analytical apparatus; and 

b) Sampling in cylinders, in which case the 
sample is transferred in a cylinder to a 
laboratory. 

Other methods may be used provided that they are 
shown to give equally representative samples on 
analysis (see Annexes A to C). 

8.3.2 Direct Sampling 

Connect the sampling valve by means of suitable 
connections {see 8.2) to an evaporating device and 
then via a T-picce (the free leg of which is connected 
to the dip-tube of a Drechsel bottle containing 50 mm 
of mercury covered by a layer of water on the carbon 
dioxide side) to the analytical apparatus. Thoroughly 



flush the connections, valves and the evaporating 
device with carbon dioxide before starting to take the 
sample. 

8.3.3 Sampling in Cylinders 

Use a cylinder of water capacity 1.4 kg or 2,0 kg, 
complying with the requirements of IS 7285 and with 
a valve at each end. 

An internal copper dip-tube of diameter at least 5 mm 
and of length equal to one-third of the length of the 
cylinder shall be brazed to the base of one valve, which 
shall be clearly identified. The cylinder shall be coated 
internally with tin [containing 1 percent (m/m) of lead] 
applied by hot dipping the cylinder after the walls have 
been descaled. 

First clean the sampling cylinder by removing both 
valves and washing the inside of the cylinder with 
carbon tetrachloride. Purge with a current of dry 
filtered air. Wash with methanol and repeat the 
purging. Degrease the valves using carbon 
tetrachloride, then refit them. The methanol and 
carbon tetrachloride used shall comply with the 
requirements specified in B-2. 

Support the cylinder vertically with its dip-tube valve 
uppermost. Before taking the sample, thoroughly flush 
the cylinder with a small quantity of liquid carbon 
dioxide, first through the top valve and then through 
the bottom valve. Repeat this flushing procedure, and 
leave the cylinder connected to the liquid carbon 
dioxide source via its lower valve. Then, with the upper 
valve closed, open the lower valve to admit liquid 
carbon dioxide to the cylinder. Partly open the upper 
(dip-tube) valve and continue filling until carbon 
dioxide snow is discharged from this valve. Close both 
valves. Open the top valve several times for brief 
intervals until only carbon dioxide gas is discharged 
from it. The free end of the dip-tube inside the cylinder 
will then be just above the liquid carbon dioxide level 
in the cylinder. 

Samples shall be analyzed as soon as reasonably 
practicable after collection. To withdraw the sample 
for analysis, support the sampling cylinder vertically 
with the dip-tube valve at the top. Connect the bottom 
valve of the sampling cylinder (liquid carbon dioxide) 
to an evaporating device and then via a T- piece, the 
free leg of which is connected to a tube as described 
in 8.3.2 to the analytical apparatus. Thoroughly flush 
the connections, valves and the evaporating device 
with carbon dioxide before starting the analysis. 

When sampling for the determination of water content, 
the connections to be above the dew-point to prevent 
condensation during purging. 



IS 15222 : 2002 



A-l PRINCIPLE 



Gravimetric determination of the water content by 
passing a sample of the gas over phosphorous 
pentoxide. 

A.2 APPARATUS AND MATERIAL 

A-2.I Two Absorption 1\ibes 

U-shape, the length of the limbs being 100 mm and 
the diameter of the tubes being 12 mm, fitted with 
side arms and ground-glass drilled stoppers. The tubes 
shall be filled with the desiccant (A-2.5) which shall 
be held in position by small pads of cotton wool. 

A-2.2 Flow Meter 

Float type, suitable for measuring a carbon dioxide 
flow of 200 ml/min to 2 000 ml/min. 

A-2.3 Gas Meter 

Calibrated for 1 or 2.5 litres per revolution. 

A-2.4 Test Sieves 

Of aperture sizes 425 ^m and 600 /xm, complying with 
the requirements of IS 460 (Part 1). 

A-2.5 Desiccant 

Sift powdered glass or clean» dry, washed sand and 
retain the portion that passes through a test sieve 
of aperture size 600 ^m but is retained on a test 
sieve of aperture size 425 ^m 

In general, follow the applicable recommendations and 
requirements of IS 460 (Part 1) and IS 460 (Part 2). 

Quickly transfer to a stoppered container (a large 
weighing bottle or small stoppered jar is suitable) a 
volume of fresh phosphorus pentoxide and add about 
half as much by volume of the prepared powdered glass 
or sand. Vigorously shake the container to mix the 
components and fill the U-tubes (A-2.1) as quickly as 
possible with the mixture. 

If it is prepared in this way, it should be easy to fill the 
tube with the desiccant. If it is not easy, it is probable 
that the phosphorus pentoxide was moist before 
addition of the powdered glass or sand. 



ANNEX A 

(Clause 53) 

DETERMINATION OF WATER CONTENT 

Prepare the desiccant in small quantities, as required. 

A-3 SAMPLING 



Take the sample in a cylinder by the method described 
in 8.3.3. About 120 g of carbon dioxide is required 
for each determination. 

A.4 DETERMINATION 

After the evaporating device, connect the exit side of 
the T'piece to the absorption tubes (A-2,1), the flow 
meter (A-2.2), and the gas meter (A-2.3) in series, in 
that order. 

Carefully open the regulating valve and absorption 
tube taps and allow the gas to flow at a rate of about 
500 ml/min for 10 min; the carbon dioxide displaces 
the air in the absorption tubes. Close all taps, 
disconnect the absorption tubes and wipe the tubes 
surfaces with a dry, soft cloth. Place the absorption 
tubes in the balance case, leave for 20 min, then weigh 
them to the nearest 0.5 mg. 

Reconnect the absorption tubes. Note the reading of 
the gas meter then allow the gas to pass at a steady 
rate of 500 ml/min to 1 000 ml/min for 1 h. 

Close the taps and reducing valve. Note the gas meter 
reading. 

Place the absorption tubes in the balance case, leave 
for 20 min, then weigh them to the nearest 0.5 mg. 

A-5 EXPRESSION OF RESULTS 

The water content, expressed as a percentage by mass, 
is given by the formula: 

54.29 (m,-m,) 



where 



m^ = initial mass, in grams, of the absorption 

tubes; 
m^ = final mass, in grams, of the absorption 

tubes; and 
V = volume, in liu*es, at 20 °C and 760 mmHg 

of gas passed, read from the gas meter. 



IS 15222 : 2002

peak at 3 460 nm. 

B.2.2 Standard Oil Solution 

Dissolve 0.020 g of liquid paraffin in carbon 
tetrachloride, transfer quantitatively to a 100 ml one- 
mark volumetric flask and dilute to the mark with 
carbon tetrachloride. 

One ml of this solution contains 200 ng of oil. 

B-3 APPARATUS 

B-3.1 Two bubblers as shown in Fig. 1. 

B-3.2 Drechsel bottle of capacity 250 ml. 

B-3.3 Flow meter, float type, suitable for measuring 
carbon dioxide flow of 200 ml/mi n to 2 000 ml/min. 

B-3,4 Gas meter, calibrated for 1 litre or 2.5 litres per 
revolution. 

B-3.5 Infra-red spectrometer and accessories, suitable 
for making measurements at 3 460 nn. 

B-4 SAMPLING 

Take the sample by the method described in 83.3. About 
700 g to 1 000 g is required for each determination. 

NOTE — A set of cylinders should preferably be retained for 
sampling for the determinaiion of oil content and should not be 
used for other purposes. 

B-5 PROCEDURE 

B-5.1 Preparation of Test Solution 

Place 100 ml of the carbon tetrachloride (B-2,1) in 
the Drechsel bottle (B-3.2) and 25 ml in each 
bubbler (B-3.1). Support the weighed sampling 
cylinder with the dip-lube valve at the top, connect 
the bottom valve of the weighed cylinder to theT-piece 



ANNEX B 
(Clause 5,4) 

DETERMINATION OF OIL CONTENT 

of the evaporating device and then to the Drechsel 
botde, the two bubblers, the flow meter and the gas 
meter in series, in that order, using short rubber 
connections. 



No carbon dioxide shall be allowed to pass to the 
atmosphere through the outlet of the T-piece. 

Weigh the cylinder, totally expand the contents of the 
cylinder through the absorption train at a flow rate of 
about 1 000 ml/min, and read the volume of gas passed 
(this serves as a check on the amount of carbon dioxide 
used for the test). 

NOTES 

1 Some evaporation of the carbon tetrachloride will take place. If 
this is excessive, slop the flow of gas and refill the absorption 
bottles, noting the volume of carbon tetrachloride. 

2 In view of the toxic nature of carbon tetrachloride, the effluent 
gas from this determination should be discharged to the outside 
air. 

Reweigh the sampling cylinder, taking care to use the 
same valve fittings as at the first weighing. Remove 
the valve not attached to the dip-tube and wash the 
inside of the cylinder with 25 ml of the carbon 
tetrachloride. Wash the interior of the evaporating 
device and valves with carbon tetrachloride and 
combine this solution with the cylinder washings and 
the contents of the bubblers. Make up the combined 
solutions to some suitable, definite volume, 

B-5.2 Preparation of Blank Test Solution 

Evaporate a volume of carbon tetrachloride, equal to 
the total volume (including any additions) of carbon 
tetrachloride used in the absorption train plus 
washings, to the volume of the combined solution 
(see B-5.i) and subsequently treat it in the same way 
as the test solution, 

B-5.3 Spectrometric Measurements 

Following the manufacturer's instructions for the 
operation of the instrument, determine the absorbances 
of the lest solution and of the blank test solution at 
the wavelength of maximum absorption (approxi- 
mately 3 460 nm). From the calibration graph (B-5.4), 
deduce the masses of oil corresponding to the measured 
absorbances, 

B-5.4 Preparation of the Calibration Graph 

Prepare suitable dilutions of the standard solution (B-2^) 
to cover the range within which the mass of oil in the 
sample is expected to be found. Measure the absorbance 
of each of these solutions as described in B-5.3. Prepare 
a calibration graph by plotting the masses of oil against 
the corresponding absorbances.

ANNEX E 

(Foreword) 

SAFETY PRECAUTIONS FOR HANDLING 



E-1 Carbon dioxide is shipped/transported from the 
manufacturer as a liquefied gas in bulk under pressure 
at low temperature; and in cylinders under higher 
pressure at ambient temperatures. All precautions 
pertaining to the safe handling and operation of 
containers, piping and equipment under pressure 
should be observed when filling fire fighting 
equipment with the medium. 

E-2 During the discharge of containers of carbon dioxide, 
low temperatures can arise through expansion of the 



liquid to gas and solid. This can present a hazard of frost 
bum. Gloves and eye protection should be worn when 
transferring carbon dioxide firom one container to another. 

E-3 Transfer of carbon dioxide should be carried out 
in a well-ventilated area or in the open air. 

E-4 Carbon dioxide is much heavier than air and can 
collect in pits, cellars and low lying areas. Care should 
be taken when entering such areas on sites where 
carbon dioxide has been used. 



IS 15222 : 2002 



ANNEX F 

(Foreword) 

COMPATIBILITY 



Carbon dioxide may be used simultaneously with other 
types of fire extinguishing media for fire fighting 



purposes, with no known indications that 
extinguishing efficiency is affected. 



ANNEX G 

(Foreword) 

TOXICOLOGY 



G-1 GENERAL 



The principal action of carbon dioxide is to cause 
suffocation, although it is mildly toxic in its own right. 

At concentrations of 3 percent to 4 percent (v/v) in 
air, the respiration rate is increased and headaches 
can be caused. 

At concentrations of 9 percent (v/v), personnel can 
lose consciousness within minutes, this being preceded 
by disorientation, visual disturbance, ringing in the 
ears, tremors, etc. 

At a concentration of about 20 percent (v/v), death 
will follow in 20 min to 30 min. 



G-2 PRECAUTIONS AND TREATMENT 

In practice, concentrations of 30 percent (v/v) or 
more are employed for total flooding systems. 
Similarly, high concentrations could be encountered 
near to the nozzles of hand extinguishers or local 
application systems. Such concentrations are highly 
hazardous for persons and special precautions 
should be taken depending upon the specific 
conditions of use. 

Persons suffering from exposure to carbon dioxide 
should immediately move or be moved to fresh air. 
Medical aid should always be sought in the event of 
such over-exposure.
